A non-transitory computer-readable medium includes a figure data generation program to cause a computer to execute a first process of displaying a drawing screen to make/edit an intended figure, a second process of commanding a processor to draw the intended figure on a surface of a workpiece to project a visible light onto a predetermined position on the surface, the processor including a visible-light source, the predetermined position having been designated by a user, and a third process of presenting a position corresponding to the predetermined position in the drawing screen.

A device generating modeled object data representing a modeled object created while supported by pillar-shaped supports using a 3D printer includes a storage to store data of a body and data of the supports, a layout determiner to determine a layout of the body of the modeled object in a building area of the 3D printer, a display controller to display an image of the body with the determined layout, a support arrangement determiner to determine build positions to create the supports of the modeled object in the determined layout, and a modeled object data generator to generate the modeled object data representing the modeled object in a state where the modeled object is created, each build position to create the support being determined by the support arrangement determiner at a locally highest point parallel to a horizontal plane and protruding thereabove in the vertical direction, the locally highest point being located at a position lower than a top end of the support.

A desired whole slice image corresponding to a whole object is created in a slice image creation device, in which a synthesis processor overlaps a target slice image created by a target slice image creation processor and a support slice image created by a support slice image creation processor. The synthesis processor determines a portion of the overlap region corresponding to a target printing region of the target slice image and/or a support printing region of the support slice image as a whole printing region to be printed, and determines a portion of the overlap region corresponding to both of a target non-printing region of the target slice image and a support non-printing region of the support slice image as a whole non-printing region not to be printed. The synthesis processor colors the whole printing region and the whole non-printing region with different colors to create the whole slice image.

In a slice image creation device, a topology construction processor constructs a topology to create a topology list of a target object model. A division determination processor determines whether or not there is a ridgeline or an apex at which the target object model is divisible in correspondence with topology groups. A division processor, in a case that, for example, there is a ridgeline that is in contact with 4 planes, divides the target object model into at least a first divided object model and a second divided object model along the ridgeline that is in contact with 4 planes. A slice image creation processor creates a first divided slice image and a second divided slice image respectively corresponding to the first divided object model and the second divided object model. A synthesis processor synthesizes the first divided slice image and the second divided slice image to create a target slice image.

In a region determination device and method, when a set target contour is an island contour representing an outer profile of a three-dimensional printing object, it is determined whether a closest enclosing contour Lmin enclosing the target contour at a closest position thereto has been set for the slice model or not. When closest enclosing contour Lmin is determined to have been set, it is determined whether the closest enclosing contour Lmin is an island contour or not. When the closest enclosing contour Lmin is determined to be an island contour, the target contour is deleted from the slice model. Then, the region of the post-deletion slice model is divided into a printing region and a non-printing region.

A cross-section data generating device includes a storage that stores therein a three-dimensional polygon model provided with color information, and a processor that executes a program to perform a shape obtaining process of obtaining a shape of an outline of the three-dimensional polygon model at a cross section that intersects the three-dimensional polygon model, and a color information obtaining process of obtaining color information of the outline at the cross section.

In a region determination device and method, when an island contour of a slice model crosses a scanning line in a first direction, the value of an internal level n is increased by a predetermined value. When the island contour crosses the scanning line in a second direction different the first direction, the value of the internal level n is decreased by the predetermined value. When a hole contour of the slice model crosses the scanning line in the second direction, the value of the internal level n is assigned to a temporary retain variable m and '0' is substituted for the internal level n. When the hole contour crosses the scanning line in the first direction, the value of the temporary retain variable m is assigned back to the internal level n. A region corresponding to a value of the internal level n, set as above, that is not 0 is determined to be a printing region, and a region corresponding to the value of the internal level n that is 0 is determined to be a non-printing region.

In a slice image creation device, a peeling processor performs peeling on a peeling line segment in a circulation direction of the peeling line segment. When the peeling reaches an intersection at which line segments of contours cross each other, an intersection information acquisition processor acquires intersection information including an intersection angle defined at the intersection by the peeling line segment and each candidate line segment connected to the intersection in a direction that is the same as the circulation direction of the peeling line segment. A transfer processor sets one of the candidate line segments that has the smallest intersection angle as the line segment to which the peeling is going to be transferred next from the peeling line segment at the intersection. A creation processor sets the line segments on which the peeling has been performed continuously as one generated contour and divides a target slice model into a printing region and a non-printing region based on the generated contour to create a target slice image.
